Hi!

I'm writing a mystery novel set in Oklahoma in 1935. The plot turns on
the use of a particular rifle and very special and unique ammunition.
I haven't been able to settle on the identity of either a gun or the
ammo. I've been doing research but there is just so much! and what I
want is very specific information. So I decided to try to find some
people who I could ask a bunch of questions.

The murders in the story are done with some kind of fairly powerful
rifle. I think anything in the .30-06 range would do. It's a hunting
rifle or a military rifle that could be used as a hunting rifle. In
fact the latter would be preferable. I need something that ejects
cartridges, so my poor detective has something to find. The owner of
the gun is a blow-hard braggart and would love to own something he
could brag about like "This was used by a general in the Great War!"
His Okie hayseed listeners wouldn't be able to tell if he was lying or
not. So military weapon of German make would be good.

The ammo is key. Then, as now, almost every household had several guns
so I need something unique. Cartridges that have German markings on
them, perhaps, or made from an unusual kind of metal.

Thank you all for any help!
